( #3333=superdoc: print w/ replies, xml ) Need Help??

Following in Ovid's footsteps, I'm trying to remove boilerplate from my code. I'm generally happy with the result, but for warnings.

I have a module with an import method. It's only purpose is to enable strict and warnings and a few other pragmas. But, I don't want it to enable all warnings, and this is where I'm a bit stumped.

package Foo; # lots of use statements here. use Import::Into; sub import { my $target = caller; 'strict'->import::into($target); 'warnings'->import::into($target, qw(FATAL utf8)); if ($] >= 5.017011) { # THIS IS THE PROBLEM LINE 'warnings'->unimport::out_of($target, 'experimental::smartmatc +h'); } }

The problem is 'warnings'->unimport::out_of($target, 'experimental::smartmatch'); turns off all warnings, not just the one I want.

unimport::out_of() is calling warnings->unimport('experimental::smartmatch'); - which I think is the same as calling no warnings 'experimental::smartmatch';. But it isn't working.

So how do enable warnings (except one) via an import sub?

update: This is Perl 5.18.1. I also fixed some formatting.
